Do Scheduled recordings hold on to capture source after reassigning channels?

[Pioneer4x4]

Since I was having difficulties with shows back to back on te two sources on one card, I decided to move everything to recording off of the composite jacks from the cable box and tune everything on it instead of the internal tuner. I went into the config and unselected all channels on the internal tuner source, and selected them all on the cable box via composite. Since doing that, I have had some shows record crap, like digital static, and the only thing I can think of is it was still via the internal tuner.

What I would like to know is if the shows were already pending before moving the channels, would the still try to record on that source. I remember reading that shows are assigned sources at time of scheduling.

If this is what happened, I guess this would be a bug, since I actually did tell it not to include those channels on that source.

Anyway, I just deleted the internal tuner source, and ALL scheduled and recuring recordings. Then I went back in and rescheduled everything. So either way, it "shouldn't" be an issue now.
